Coronado 60mm 雙堆疊轉接環 - AP186

Finally got around to stacking my SM60 and this ring made the whole setup click into place effortlessly. The threads are machined cleanly, so the etalon seated perfectly without any wobble or tilt. Took about two minutes to swap from single to double stack and the sun looked incredible.

The threads on this adapter ring are precise and smooth—it screwed right onto my OTA without any fuss. It's solidly machined and holds the etalon perfectly centered, exactly what you need for critical solar observing.

Finally got my double stack dialed in and this ring is the missing link. The threads are machined perfectly so the etalon screws on tight with zero play, and I can swap it between scopes in under a minute.
